Abstract: Base on experiments on prototype of air-source transcritical CO2 heat pump water heater at a range of
running ambient temperature (-15℃~35℃) and a range of hot water outlet temperature (55℃~80 ℃)
corresponding to each running ambient temperature, major influence factors on system performance of air-source
transcritical CO2 heat pump were detailed analyzed in the paper, which point out that ambient temperature and
inlet/outlet water temperature were fundamental influence factors of system performance, and in the paper the
optimal pressure which is the vital influence factor of system performance was discussed emphatically. Furthermore,
it is presented how to further improve system performance base on all influence factors.
Keywords: air-source transcritical CO2 system,heat pump water heater, COP, optimal pressure
